Myst: Mouse cursor hangs while animations are played

ScummVM 1.10.0git140-g87e2fbb
OS: Windows 10
Game: Myst (no ME)

While animations are played, the mouse cursor cannot be moved. As soon as the animation is stopped, the mouse cursor moves again.

To simply reproduce this, move to the left right at the beginning of the game to enter the underground projector room. Move in front of the panel that controls the projector. Click on the button that opens the control panel and try to move the cursor away immediately - it won't work until the animation is finished.

Next, move to the projector itself and click on the button that triggers the projector to change it's picture. Again, move the mouse cursor away and you will see that you can't move it until the "click" of the button is finished.

I managed to install the original Myst Masterpiece Edition on my system. (Yes, it even runs in Windows 10 64bit without compatibility mode. You need to install Quicktime 6.5.2 for it to have proper video).

I noticed that in the original game, the cursor is disabled/invisible for the duration of the animation. I noticed that on the animation for said control panel. The original game behaves like ScummVM for the "click" on the projector button though.

I've made it so that the cursor is allowed to move while the transitions are drawn. I think it's nicer that hiding the cursor.
